Cooling Sight Glass
Customer performs tests for the research industry. One of their tests it to heat a product to 1100C. The radiant heat is overheating the glass and seals on the observation window. Using a Model 110012SS 12" (305mm) Stainless Steel Super Air Knife, a constant flow of air dispersed over the glass has kept it cool. It worked well with using only a small amount of compressed air.
